Electronic device and method for controlling power supply, and nontransitory storage medium

An operation method of an electronic device, the operation method comprising:

• connecting to an external electronic device through a pogo interface comprised in input/output circuitry of the electronic device;
• applying a first output voltage to the pogo interface to supply power from a battery of the electronic device to the external electronic device;
• receiving information related to the external electronic device from the external electronic device through the input/output circuitry while applying the first output voltage to the external electronic device;
• based on the information related to the external electronic device, maintaining the first output voltage or changing the first output voltage to a second output voltage;
• and
• applying the maintained first output voltage or the second output voltage to the pogo interface.

A non-transitory storage medium storing one or more programs,

• wherein the one or more programs comprise instructions that, when executed by at least one processor of an electronic device, cause the electronic device to perform:
• connecting to an external electronic device through a pogo interface comprised in input/output circuitry of the electronic device;
• applying a first output voltage to the pogo interface to supply power from a battery of the electronic device to the external electronic device;
• receiving information related to the external electronic device from the external electronic device through the input/output circuitry while applying the first output voltage to the external electronic device;
• based on the information related to the external electronic device, maintaining the first output voltage or changing the first output voltage to a second output voltage;
• and
• applying the maintained first output voltage or the second output voltage to the pogo interface.
